There is a ticket about this, but no conclusion about whether the vote happened or not (https://trac.einsteintoolkit.org/ticket/1410).  The minutes of the 8th August meeting do not mention it.  I think the discussion started briefly at the end of a later telecon but there was not enough time, and it hasn't been brought up again.  Specifically, I think the major objection to Boost is its size, which can be ameliorated by changing the way the repository is structured, or the way that external thorns work (e.g. downloading the library tarball when needed, rather than on checkout).  The toolkit is only supposed to contain components which have been agreed on.  Since Boost is not yet (as far as I know) part of the toolkit, I don't think it should be downloaded with the toolkit by default.  It should be commented out in the thornlist, so that users can add it back in if they want, until we agree on whether it should be included, and in what form.

I don't think we should list thorns in our manifest which are not part of the Einstein Toolkit. I would rather remove it completely. Otherwise, we'll have a set of thorns that are "not officially in the ET", but "mentioned in the manifest for convenience".

Either adding Boost to the ET (after discussion and addressing the issues), or adding it manually to the thorn list if one wants it even though it is not part of the ET are not difficult.

I removed the automated download, and I suggest to remove Boost completely.

There are a few other thorns "in limbo", e.g. MemSpeed. Let's follow the proper procedure here, including a review -- that can't hurt...
